← ScienceWhich outcome reduces signal strength after beta minus decay in potassium-40?
A)Attenuation via increased electron interaction✓
B)Amplification through neutrino coherent scattering
C)Modulation by positron annihilation cascade
D)Reflection from daughter argon recoil
💡 Explanation
Due to beta minus decay, high-energy electrons released increase interaction with matter, causing attenuation because kinetic energy will be imparted via collisions. Therefore, signal decays rather than being amplified beyond signal strength, as neutrino scattering/others are less impactful.
